Good thinking ;), now I don't:

    BOOST_MPL_ASSERT_IS_SAME(iter::type, int);

F:\home\depot\mpl_17_jul_02\libs\mpl\test\find.cpp(44) : error C2039:
'is_same_test_dummy' : is not a member of 'integral_c<int,7>'

Which errors? In my situation (9 different compilers set up as external
tools) the IDE has no knowledge of where the resulting .exe file will
reside, let alone running it and navigating through the results. The fact
that I have to run the test after compiling it is already a pain. Anyway,
it's getting off topic.

The bottom line is that right now I am perfectly satisfied with compile-time
only tests and not going to invest any significant energy into porting them
to unit-test framework for the sole purpose of using one. When there will be
a clear need, I will reconsider.
